Hey William, thanks for reaching out!
Usually there isn't a way to get just the replacement pin, but if you have a kit like the Master Lock # 3794DAT, we have some of it pieced out and you could get just the locking pins as part # 2866DAT or part # 2848DAT. This would come with an additional lock, but you would be able to simply swap it out to the one you currently have so everything is still keyed alike.
If you let me know what specific lock kit you have, I'd be happy to see if we have just the pins available, or at least a smaller kit.
